Many customers like Gym King for comfortable, well-fitting gym and streetwear, plus fast order fulfilment. Reviews often single out hoodies, tracksuits, and hats as good value with attractive colours. Several shoppers describe delivery, refund, and contact problems that remained unresolved after purchase. Sizing varies by product, and some leggings and seams have failed after limited wear.
Examples from available reviews (Jan 2023 – Mar 2026).
Great quality clothes, quick delivery and decent prices.
“Really great quality clothes, quick delivery with decent prices.”
£200 order not delivered and no communication or replies.
“£200 order not delivered.. no communication no replies to my messages nothing!”
Sizing is terrible; sizes run much smaller than other brands.
“The sizing is terrible- I went one size up from all other hoodies I have and top supplied too tight.”
Leggings split after only five wears, leaving reviewer gutted.
“they've split on the bum”
When orders arrive as expected, reviewers mention quick dispatch and helpful staff. A larger group describes missing or incorrect items, tracking numbers created for parcels that never show up, and long delays or failed refunds. These fulfilment problems repeatedly drive customer dissatisfaction.
Many reviewers say tracksuits and shirts feel like good value at the listed prices. Return costs and reduced refunds come up often, with some customers saying they cancel out the value. A smaller number directly describe items as feeling cheaply made.
Many shoppers describe easy online ordering and clear delivery confirmations when purchases go smoothly. Sizing inconsistency appears often, with items reported as both smaller and larger than expected compared with other brands. Several reviews praise the site’s usability, while noting that sizing guidance is not detailed enough.
Many customers point to sturdy fabric, good fit, and pleasing colours for coats, hoodies, and sets. Another clear theme is durability issues: leggings splitting at seams, fraying, and materials turning fuzzy after minimal use. Praise for quality and complaints about wear show up across different product lines.
Some reviews mention helpful delivery updates and tracking when orders move normally. A strong negative theme focuses on emails going unanswered, missing tracking on high-value orders, and no reply to return questions. These communication gaps often sit alongside refund and missing-item problems.
Reviews divide between high-satisfaction purchases focused on the product and delivery, and low-satisfaction cases driven by post-purchase service. Positive experiences emphasise fit, comfort, and timely fulfilment. Negative experiences focus on unresolved returns, missing parcels, and no customer contact, creating a clear split in sentiment.
